10' Claims. ((31%. 21-495) (Granted. under. Title 35, U. 8'. Code(1952), see. 266) The invention described herein, if patented, may bemanufactured and used by or for the Government for governmentalpurposes, without the payment to meof any royalty thereon.

The invention relates to head coverings and more pan ticularly to headcoverings of the type which include one or more elastic inserts in theside wall area so as'to allow one side of the head covering to fit headsof several different sizes.

*Such head coverings are objectionable when used in cold weather becausethe elasticized knit fabric which forms the most satisfactory elasticinsert particularly when stretched is highly pervious to air and permitsthe entry of drafts to the headwhereby the wearer is more susceptible tohead coids and like ail'mcntsa The desirabilityof" providing means forbarring the entry of drafts intosuch a head covering is obvious;

With the toregoing in view, it is an object of the invention to providean improved elasticized-cap which includes a novel means restricting thepassage of air or drafts therethrough.

A further object is to provide an improved cap of this type wherein atleast one-section of the cap is of two ply construction with free loweredges, each: ply including substantially impervious and perviousportions, one of said portions being elastic, and the imperviousportions of the plies being entirely ofl'set to provide a meansrestricting the passage of air or drafts therethrough.

Other objects and advantages reside iirthe particular structure anddesignoftheinvention, the construction and design of the severalelements, combinations and subcombinations oi such elements, all-.ofwhich will he readily apparent to those skilled in. the art uponreference to the attached drawing in connection with the followingspecification whereinthe invention is shown, described and claimed.

In the. drawing:

Figure l is a perspective view taken; from above of a head coveringincluding the invention;

Figure 2 is aview like Figured but taken frombel'ow;

Figure 3 is a longitudinal, vertical sectional view taken substantiallyon the plane of the line 33 of Figure 1;

Figure 4 is a bottom plan view of the head covering;

Figure 5 is an enlarged, fragmentary, vertical sectional view takensubstantially on the plane of the line 55 of Figure l; and

Figure 6 is a view like Figure 5 but taken on the plane of the line 6-6of Figure 3.

Referring specifically to the drawing wherein like reference charactersdesignate like parts in all views, 10 designates any suitable headcovering. In the embodiment illustrated, the head covering 10 comprisesa cap and includes a visor 13 and a crown formed of a top piece 11 andside wall 12. The top piece 11 and visor 13 may be of any suitableconstruction but the side wall 12 is preferably formed of two plies ofsubstantially air impervious inelastic material. In at least one sectionof the side wall 12 the inner ply 14 and the outer ply 15 ice areconnected together onlyalong their upper edges by the top seam-.16 so asto have free lower edges 17 and 18- defining a'n inverted, open pocket19. In the embodiment illustrated thecap 10 has two side sections soformed, one on each side of the visor 13. Preferably and as: best seeninFigure 5, the lower portion of each inner ply 14 of each pocket 19 isitself formed of two plies 2'9 and 30 which are seamed together alongtheir lower edges as at 21'. The narrow ply 30 is between the plies 15and 20; Its upper edge: is seamed tothe inner ply 21F at531'. Elsewherein the side Wall- 12- on' both sides of the pockets 19, the inner ply-14 Figure 6, is preferably of single ply construction and connected tothe outer ply 15 by the bottom edge seam 22 as well as the top seam 16To elasticize the side wall 12, each outer ply- 15 of each pocket 19includes an air perviousportion 230i any suitable elastic material suchas elasticized knit material. In like manner, each inner ply 14 of eachpocket 19 includes, an air pervious portion 24 of like material. Thepervious portions 23 and 24 preferably extend the entire height of theside wall 12. Also, such portions 23 and 24- are entirely ofiset toprevent passage of air through the side wall 12. Preferably, thepervious portions 23 and 24 areoffset substantial distances, at least asgreat as the width of each pervious portion. Themost efiicientarrangement'is the one illustrated wherein the pervious portions 23 and24 are offset asfar as possible so that the outer portions 23 are at oneend of the pockets 19 and the inner portions 24 are at the other ends ofsuch pockets:

It follows from the foregoing that a single size of head coveringaccording to the invention will readily adapt itself to heads of severalsizes. At the same time, this uniquemean-s of the invention prevents theentry of cold air throughthe side wall 12 despite'the perviouselasticizin'gportions 23 and 24. In this connection, it should be notedthat the pressure of the wearers head against the side wall12eifectively forces plies 14 and 15 together and'closes each pocket 19against the passage ofair from an outer pervious portion 23longitudinally of a pocket to the related inner pervious portion 24-.Thus, for all air passage purposes the pockets 19 do not exist. Theyarenecessary topermit lateral sliding of the inner and outer pliesrelative toeach other as the side wall 12 expands or' contracts to fitheads of different sizes. At the same time, animpervious wall of double;thickness has been provided in the sweat band area throughoutsubstantially the entire side wall 12. Moreover, while the cap shown isprovided with two anti-draft sections at specific locations, it isobvious that fewer or more of such sectionscould be provided atdifi'erent places.

Consequently, while there has been shown and described what is nowconsidered to be a preferred embodiment of the invention, it should beunderstood that the same is susceptible of other forms and expressions.Thus, the invention is not limited to the precise structure and designshown and described hereinabove except as hereinafter claimed.
